Is Carfilzomib a chemotherapy drug?

Carfilzomib (Carfilzomib) is not a traditional chemotherapy drug, but a targeted therapy drug commonly used to treat multiple myeloma (Multiple Myeloma) and other related blood cancers. Unlike traditional chemotherapy drugs, carfilzomib interferes with the survival and proliferation of cancer cells through a specific mechanism, rather than killing cancer cells through toxic effects. Its mechanism of action involves inhibition of the proteasome, a cellular organelle responsible for protein degradation. By blocking the normal function of the proteasome, carfilzomib prevents protein degradation in cancer cells, leading to the accumulation of toxic proteins inside the cancer cells, ultimately leading to the death of the cancer cells.
